ama- 'IMPROVEMEN'Ii IN AXLES, FOR: CRRIAG-ES.

The Schedule referre to in these Letter-s Patent and making part of theaauue.

To all whom,iti/may'concern e Be itv known that I, SAMUEL Folmns'rnn, ofthe city and county'of Allegheny;v and State of Pennsylvana, have'invented a new and useful Improvernent in Spindle for Oarriage-Axles ;4and I do hereby de-. clare that the following is a full, clear, andexact description thereof, reference being had to t-he accompa-` nyingdrawing, and to `the letters of reference inarked thereon.. i, f

, 'The nature of Lny iuventiou consists in so constructing the spindleof a carriageeaxle, that it shall fit Vn'eatly, and closely to the npperandilower sides of the axle, and leave, on the back and front sides ofvit, an oilcharnher;` and also, in providing the spindle with aclip-flange 4for bracing'and cla'ruping the wood and spindle to theaxle. i

`To enable others skilled'in the art to make and'use myyinvention, Iwill rproceed. to describe its construction andioperation. i

i In the accompanying drawing, which forms part of my `specification- Vv Figure 1 is a side viewofemy improvement in spindle forcarriage-axl'es. i

' Figure 2 is a longitudinaltsection of the same. Figure 3 is atransversc section of the same, when cut through at line y, fig. 1.

Figure 4 is an end view of 'axle and spindle. In the accompauying drawin--v f i A-represents thev spindle, which may be made of cast-iron orsteel, and is cored out so asl to fit neatly and closely to the upperand lower sides of the axle B,`as shovmat o, in figs. 2,3, and 4. Bythus fittilng the axle' in the spindle, it is not liable tovbreak' oli'at the inner end-of the spindle, or in the spindle, for it will have novertical motion. The innerfan'd outer ends of the opening in the spindleare fi'tted neatly and closely-to the axle B, for the p'urpose ofpreventing any side motion of the spindle on the axle. On the front andback sides of the axle B, are oilchambers w, which communicate with theinterior of the hub of the \fvheel of the carriage, through the mediurof the openin'gs i.

i The charnbers x are filled with oil through the openings sin the endofthe spindle'A.

On the inner end of the spindle is a flange, e, which is provided withopenings for the ends of the clip' f.

By means of this flange e and the clip f, the wood part O, of the axle,and the spindleA may be secured, 'bracechaud clamped firmly to theironpart B, of the axle.

, .l represents a screw-nut, which is used for the purpose o fpreventing any motion endways of the ,spindle on the axle. By illing theoilvchambers :ze-,with oil, the spindle B will'always be properlylnb'ricated- Having thus described` the nature, construction, andoperation of myimprovement in spindle forv oarrage= axles,

\What I claim as of my invent-ion, is

Providing the spindle A with the clip-fiange e, and so constructing thebore of the spindle that it Will fit neatly and closely to the upper andlower sides of `the axle B, and leave oil-Chambers a: on the back andfront sides of it, as herein described, and for the purpose set forth. 1i
